| 摘 要： | 针对焦化废水治理难题，将传统生化处理工艺A／A／O改造成A／A／O＋MBR组合处理工艺，运行结果表明：A／A／0＋MBR组合工艺对NH3-N去除效果好，处理出水NH3-N浓度一般为5-10mg／L，CODcr浓度为200mg／L左右，较A／A／O工艺有明显改善和提高；剩余污泥产量为系统改造前的10％左右，大大节约了污泥处理处置成本；MBR膜组件模块化自动控制，简化了操作维护，有效减缓了膜污染。

| Abstract: | Advanced treatment for coking wastewater was investigated experimentally by A/A/O＋MBR combination treatment pro- cess, due to the water quality usually could not meet the discharge standards after conventional biological treatment A/A/O process. The results showed that A/A/O＋MBR was more effective than A/A/O process for removing ammonia nitrogen （NH3-N） and other refractory compounds. The concentration of NH3-N and CODcr after the treatment by A/A/O＋MBR process were 5-10 mg/L and 200 mg/L, respectively. Moreover, it was found that the excessive sludge yielded reduced by 10 % relatived to the system before the transformation, which was a significant reduction in the cost of sludge treatment and disposal. Also, modular-automatic control of MBR membrane modules simplified the operation and maintenance, and eliminated the membrane fouling effectively. |
